2. Laboratory flask - Wikipedia

   en.wikipedia.org/wiki/Laboratory_flask

   Distillation flasks are intended to contain mixtures that are subject to distillation, as well as to receive the products of distillation. Distillation flasks are available in various shapes. Similar to the reaction flasks, the distillation flasks usually have only one narrow neck and a ground glass joint and are made of thinner glass than the ...

3. Round-bottom flask - Wikipedia

   en.wikipedia.org/wiki/Round-bottom_flask

   Flat-bottomed flask: A flask with similar uses as the round-bottom flask, but with a flat bottom that allows it to stand on a level surface.; Florence flask: A flask similar to the flat-bottomed flask that has round bodies and either a round bottom or a flat bottom so that one can stand the flask on a level surface.

4. Laboratory glassware - Wikipedia

   The task may require a piece of glassware made with a specific type of glass. The task may be readily performed using low cost, mass-produced glassware, or it may require a specialized piece created by a glass blower. The task may require controlling the flow of fluid. The task may have distinctive quality assurance requirements.

5. Fractionating column - Wikipedia

   en.wikipedia.org/wiki/Fractionating_column

   This process is the origin of the name fractional distillation or fractionation. Distillation is one of the most common and energy-intensive separation processes. Effectiveness of separation is dependent upon the height and diameter of the column, the ratio of the column's height to diameter, and the material that comprises the distillation ...

6. Erlenmeyer flask - Wikipedia

   en.wikipedia.org/wiki/Erlenmeyer_flask

   Method of swirling an Erlenmeyer flask during titration. The slanted sides and narrow neck of this flask allow the contents of the flask to be mixed by swirling, without risk of spillage, making them suitable for titrations by placing it under the buret and adding solvent and the indicator in the Erlenmeyer flask. [7]

7. Florence flask - Wikipedia

   en.wikipedia.org/wiki/Florence_flask

   A Florence flask has a round body, a long neck, and often a flat bottom. It is designed for uniform heating, boiling, distillation and ease of swirling; it is produced in a number of different glass thicknesses to stand different types of use. They are often made of borosilicate glass for heat and chemical resistance

8. Volumetric flask - Wikipedia

   en.wikipedia.org/wiki/Volumetric_flask

   These flasks are usually pear-shaped, with a flat bottom, and made of glass or plastic. The flask's mouth is either furnished with a plastic snap/screw cap or fitted with a joint to accommodate a PTFE or glass stopper. The neck of volumetric flasks is elongated and narrow with an etched ring graduation marking. The marking indicates the volume ...

9. Condenser (laboratory) - Wikipedia

   en.wikipedia.org/wiki/Condenser_(laboratory)

   The Snyder column is a wide glass tube divided into sections (usually 3 to 6) by horizontal glass partitions or constrictions. Each partition has a hole, into which seats a hollow glass bead with an inverted "teardrop" shape. Vigreux-like glass "fingers" limit the vertical motion of each bead. [24]
